Secure Outsourcing of Network Flow Data Analysis

In this paper, we identify a new and challenging application for the growing field of research on data anonymization and secure outsourcing of storage and computations to the cloud. Network flow data analysis is of high importance for network monitoring and management. Network monitoring applications reveal new challenges not yet addressed in the secure outsourcing literature. The secure and verifiable outsourcing of computation on anonymized network flow records provides a practical tool for network operators in order to harness the cloud benefits, which untapped until now because of privacy concerns. We present representative use-cases and problems, and identify sample related work that can be utilized for developing an effective solution.
